HINGE.

SPECIFICATION forming part of Letters Patent No. 276,540, dated April24, v1883. V Application filed January 5, 1883. (Model.)

Z'o all 'whom it may concern:

Be it known that I, THOMAS L. RIVERS, a citizen of the United States,residing at Mount Vernon, in the county of Jefferson and State ofIllinois, have invented a new and useful Hinge, of which the followingis a speciication, reference being had to the accompanying drawings.

This invention relates to hinges of that class which are double-jointedand non-projecting; and it consists in certain improvements intheconstruction and arrangement of parts.

In the drawings, Figure 1 is a plan view of a joint having my improvedhinge. Fig. 2 is a like view taken from the inner side. Fig. 3 is atransverse sectional view thereof. Fig. 4 is an end view of the hingedetached.

Referring to the drawings, A designates the hinge, which is formed witha back plate, B, to which is hinged at each side edge, C C, a plate, D,by which the hinge is secured in position. These joints Eat the junctionot' the hack of the hinge and the securing-plates at each side,may beformed in any ordinary or suitable manner.A

To the outer face of each securing-plate D is secured an auxiliaryplate, F, having its edge projecting from the plate D at its joint E, soas to form a ange, G, as shown. This ange G forms a stop to the movementof the plate D, to which it is secured, by engaging the hack plate, B,when the hinge is turned to the po-. sition shown in dotted lines, Fig.3 of the drawings, and, by reason of this engagement, causes the joint Eat the other side ot' the hinge to operate when it is desired to turnthe hinge tothe positionshown in dotted lines, Fig. 4 of the drawings.

H designates a T-plate, the stem I ot' which extends between the jointsE E, while its head J forms aninterior plate corresponding to the plateB. The head J of the T-plate is of sufiicient width to enable its sideedges, K K, to

, form stops for the securing-plates D D when the hinge is closed; andby reason of this engagement with the said plates D D the hinge willclose squarely and neatly, and the plates D D cannot be forced furtherlinwardly by the weight of the boards or strips to which the hinge issecured.

My improved hinge is secured to the adjoining edges L L of the portionsM M, to be hinged together by screwsN or their equivalent, which passthrough the securing-plates D D, a plate, O, being also preferablyinterposed between the heads of the screws and the inner surface of theplate D. Mortises P P are formed, one in each edge L, to receive thehalf Ot' the hinge at that side.

The operation and advantages ot' my invention are obvious. The hinge issimple and. durable in construction, and it can be manufactured at acomparatively minimum cost.

Itis evident that the iiange G can be formed iptegral with thesecuring-plate D, in which case the plate F is dispeusedwith.

Iam aware that hinges of this double-jointed non-projecting constructionhave been heretofore made with a back plate to which are hinged thesecuring-plates, which latter are provided with lugs that engage theback plate, such a construction and arrangement being shown in thepatent to Pfantz and Franck, No. 255,809, April 4, 1882.

I am also aware Ot' the patent to Morgan, No. 232,747, September 28,1880 5 but I do not wish to be understood as claiming broadly theinvention embodied in either of these patents, my claim being for my ownnovel construction and arrangement of parts.

VI claim as my invention- As an improvement in non-projecting hinges,the combination ofthe back plate, B, the plates D I), hinged to eachside the plate B, and serving to secure the hinge in position, theiianges or extensions G, projecting above the plates D D, and arrangedto engage the outer face of the back plate, B, and the T-plate H,

having its head J, forming an interior plate,

extending across the hinge from sido to side, and serving to providestops for the plates D D when the hinge is closed, and having its stem Iextending up betweenthe joints ot' the plate B and plates D D to theformer, and Serving to secure the said back plate and interior plate orhead J together, as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.

THOMAS L. RIVERS.
